Application" flied May :In one or its aspects niy invention may be saidlto have for its obiecttoj produce a locking'pawl device for stick,Yoperating on the described and claimed the shoe I oif the shade saineprinciple lasv that in my prior application, Serial No.5%,319Qliledlrlai'ch 13,1922; the device being' somewhat simpler inconstruction than the specific device 'illustrated' in theaforesaid'application.

Viewed in another tion? may ybe saidV to overcome the rattling presentin shade sticks they are carriedfare running.,v

while the pawls simply direction as viewed in Fig. lland, trail idlyalongvthe frame. When the "finger pieces arereleased `at the end offadownward pull onr the shade,- the spring in the shade roller tends swingin a clockwise to roll up the shade, thereby raising the'shade stick.At'the instantvthat the shade stick starts to rise, the pawls becomeactive, gripping the ginning rection.

l or plug of felt or rubber Vventing the striking of metalagainst metal,I have placed within the shade stick, near each finger piece, a suitablesound-deadening cushion 11 that serves as a. bearingfor the rod. Themember 1l may consist of a simple block held in place between twofollowers 12, l2 fixed within the stick on opposite sides of suchmember; the member 11 vfitting snugly upon the rod 6, while the membersl2 are provided with comparatively large openings 13 through which therod passes.v The cushion prevents vibra-tion of the inner end of the rodto such an extent that the rod will not come in contact with any part ofthe followers.

If desiredhthe anti-friction wheels may be made of libre or othernoise-deadening material, thus reducing the slight amount of noise thatlcan be caused by metal wheels.

In Figs. 2-5 I have shown a slightly modied cushionarrangement in whichthe cushionsare located in a capsule that is inserted in the shade stickas a complete unit. The capsule may be made out of a single piece ofsheet metal shown in its flattened condition in Fig. 5. The body portion14 of the blank is substantially a vrectangle having similar elongatednotches l5 in two opposed sides.`

block 2l may be provided with still another projection 23 that will fitinto the slot duced by the bringing into registration each other of thenotches l5. After the blank has been formed into a cylinder with theearsv or lugs 18 and 19 directed inwardly, the cushions 24 are insertedin the ends of the device and, when the disk-like ears 16 are bentlater- Yally to form the endsof the cylinder, the

cushions will be clamped in place between these ears and the lugs 18 and`19. This comple-ted capsule is then inserted in the shade stick, andthe rods are passed through the cushions and provided with theusual'finger pieces. The block 21 serves both as a stop to .limit theinward movement of the rods, and

also as a point of attachment for an escut-ch- Vsule and should 'tend tochatter, therewvould be no The blank is bent prowith Lesevee eon platewhich is in passing' into the block 21. y

The hole 17 in thel ends of the capsule are snii'iciently large toprevent the Vrods from comingin contact with the metal of thecaptherefore even though the rods place by yscrew -26 metal to metalcontact noise.

While I have illustrated and described and consequently no with'particularity only a single preferred form of my invention, togetherwith a slight modification, I do not desireto be limited to the exactstructural details thus illustrated and described; but intend toCoverall forms and arrangements which come within 'the terms employedinthe definitions of my invention constituting the appended claims.Iclaim: l 1. rlhe 'combination with a shade stick, of a shoe at an endthereof provided with anti-friction'devices adapted tov ride along astationary frame member, and an L-shaped pawl pivoted at the anglethereofto the-shoe so as to be capa-ble of swinging by tween a positionin which one of its arms is parallel with the rod and projects out past`the lineof contact of the 'said anti-friction in which the other armlies parallel to the 'rod-and projects out past said line.
